Is "Turn off screen" supposed to work?

1

Hi,

just a quick question, is the feature “Turn off screen” in the Screensaver preferences currently supposed to work? I have two different PCs and with both of them it’s not working. The screensaver itself starts, but it never turns off the display.

Both of the PCs have Intel integrated GPUs, connected via DisplayPort:

 8449 0xffffffffb5f90000 0xffffffffb5f9b000     0          0 /boot/system/add-ons/kernel/drivers/dev/graphics/intel_extreme
 8475 0xffffffff8217c000 0xffffffff8217e000     0          0 /boot/system/add-ons/kernel/drivers/dev/graphics/framebuffer

The following entries to the syslog are made when the screensaver activates and the display is supposed to turn off:

KERN: intel_extreme: IsConnected: Digital Display Interface C PortRegister: 0x2004200

I’m on hrev59601 but as far as I remember, this never worked for me.

With kind regards,
Egon

It’s supposed to work, but maybe the driver is missing some support for DisplayPort or there is some other problem leading to the DPMS command sent to the display not working or getting lost somewhere along the way.

Thanks for the reply, i’ve created a new ticket for this.
